1. Start video
2. Put to the background and back to foreground right away or switch to a different tab and return
Actual result: Video is not restarted, also visibilitychange event is not fired
Issue is not reproducible on IOS 14.7
Can be tested on WebRTC sample - https://webrtc.github.io/samples/src/content/getusermedia/gum/
> visibilitychange event is not fired
This seems like it would have an even broader impact.
I can reproduce as well, this seems like a fallout of moving to GPUProcess.
We should probably notify muted state when getting interrupted from GPUProcess, instead of muting the source (which stops the underlying source and ends up removing the possibility to be notified of the unsuspension).

Nit: I think the would be better as `setMockCameraIsInterrupted`.

Just tested the repro steps on iOS 15.1 beta 4 and still encountered the issue. Was this expected to be fixed in this release?
